The full opening of the northern shipping line puts forward a great challenge for the safety of polar ships, the presence of floating ice increases the possibility of collision between ship and sea ice. However, due to the complex mechanical properties of sea ice, a reasonable description of its material constitutive relation is the main factor affecting the accusation of calculation and analysis. In this paper, a constitutive model of ice material considering the effect of temperature is presented, a user-defined subroutine is developed and embedded into the finite element software LS-DYNA. Based on this, the damage and deformation characteristics of the ship structure and ice is studied, and effects of collision scenario parameters are discussed. The results of this paper can provide reference for the design and manufacture of polar ships.
